Two parents moving into a new house attempt to pull a large crate down a large hallway. One parent applies a force of magnitude 150 N directed 45 degrees to the direction of motion, while the other parent applies a force of 120 N on the other side of the direction of motion. If they move the crate 15 m and perform work at 2.6 kJ, at what angle to the direction of motion did the second parent pull on the crate?
A) 54 degrees
B) 30 degrees
C) 60 degrees
D) 34 degrees
E) 56 degrees
